Any recomendations on MP3 players?

[GreenSalsa]

Hey guys,

I am heading downrange and am interested if anyone has any opinions on portable music devices (MP3 players). I am looking for a MP3 player with the following characteristics;

Battery powered (I want to avoid the internal rechargeable battery, I will be in a mixed austere / office environment and recharging might present a problem)

1 GB or larger in memory (Larger is better, I intend to use it to hold photos of family and use it to transfer emails to my personal laptop)

I have done some preliminary research but can’t seem to find a player bigger than 256 MB that is powered by a battery. I love the idea of the Dell DJ model with the 20 GB of memory but it has a rechargeable battery. If anyone has any recommendations on what has worked good for you please let me know,

Thanks again,

GreenSalsa
